Larger Kb values or smaller pKb values indicate stronger bases. The pKb value of ammonia is 4.75, and aliphatic amines, with a +I effect of alkyl groups, are stronger bases (pKb range: 3 to 4.22). Aromatic amines, with electron-withdrawing aryl ...

Amines react with mineral acids to form ammonium salts, demonstrating their basic nature. The basic character of amines is better understood through their Kb (base dissociation constant) and pKb (negative logarithm of Kb) values.

Amines exhibit basic character by reacting with acids to form salts. Amine salts, soluble in water but insoluble in organic solvents like ether, can be regenerated to the parent amine when treated with a base such as NaOH.

Amines are reactive due to the difference in electronegativity between nitrogen and hydrogen, as well as the presence of an unshared pair of electrons on the nitrogen atom. The number of hydrogen atoms attached to nitrogen determines the course of ...

The order of boiling points for isomeric amines is Primary > Secondary > Tertiary. Boiling points of amines, alcohols, and alkanes with similar molar masses generally follow the trend Amines > Alcohols > Alkanes.
